Ammonium Chloride (2025)

Ammonium chloride ( ) is an inorganic compound best known as a white crystalline salt. Traditionally called , it is naturally occurring in volcanic regions and is a critical industrial byproduct of the Solvay process used to produce soda ash. The "Sixth Taste": A Biological Breakthrough

: It is a vital soldering flux , removing oxide coatings from metals to allow for better solder adhesion. ammonium chloride

: This taste likely evolved as a survival mechanism to help animals and humans avoid consuming decaying organic matter or waste, where high levels of ammonium are common. Ammonium chloride ( ) is an inorganic compound

: Researchers at the University of Southern California identified that the OTOP1 protein channel—originally known as a sour taste receptor—is uniquely activated by ammonium chloride. : This taste likely evolved as a survival

Recent scientific studies have proposed that ammonium chloride may represent a , joining sweet, sour, salty, bitter, and umami.

: In conservation science, it is used in electrolytic reduction to remove corrosion from ancient metal artifacts.
